TypeLoadException in Release using Behaviors with an ICommand

[alove-kahua]

Describe the bug

Using a Behavior that has an ICommand property fails to run in Release build when using a standard Binding in XAML as such:

<Interactivity:Interaction.Behaviors>
    <Core:EventTriggerBehavior EventName="PointerPressed">
        <Core:InvokeCommandAction Command="{Binding TestCommand}" />
    </Core:EventTriggerBehavior>
</Interactivity:Interaction.Behaviors>

The exception is as follows:

Exception thrown at 0x755FA6E2 (KernelBase.dll) in CommandIssue.exe: WinRT originate error - 0x80131522 : 'System.TypeLoadException: Could not find Windows Runtime type 'System.Windows.Input.ICommand'.

This issue does not occur when the WCT is not referenced or if running the Debug build.

• Is this bug a regression in the toolkit? If so, what toolkit version did you last see it work:

Steps to Reproduce

CommandIssue.zip

• Can this be reproduced in the Sample App? (Either in a sample as-is or with new XAML pasted in the editor.) If so, please provide custom XAML or steps to reproduce. If not, let us know why it can't be reproduced (e.g. more complex setup, environment, dependencies, etc...)

Steps to reproduce the behavior:

1. Given the following environment (Sample App w/ XAML)
2. Build in the Release Configuration.
3. Start debugging the application from Visual Studio (while still in Release Configuration).
4. See error

Expected behavior

The exception does not occur and runs correctly.

Based on the above repro above i am seeing this error.
Unhandled exception at 0x09185F61 (Windows.UI.Xaml.dll) in CommandIssue.exe: 0xC000027B: An application-internal exception has occurred (parameters: 0x0AC7EF48, 0x00000005).

Let's see if any community member can take a look at the code.

@Kyaa-dost You can get more details if your Debugger type is set for Mixed (Managed and Native) in the project properties.

Hi, we are facing the same issue, even with Debug builds.

I believe this to be the same issue we're tracking with WinUI here, though in that case we're only seeing the issue in Debug mode.
